Inside the World of Backstreet Castrators, Cutters and Eunuch-Makers :
Some people born with penises and testicles want to keep the former, but lose the latter—though some choose to keep their empty scrotums. (There is a dedicated Reddit forum for the latter group to share photos of their genitals: Empty Sacks, “for those who had the balls to give theirs up.”) Others want to keep the genitalia they were born with and add new genitalia on top. ... (Mexico and Thailand have both been hot spots for quick-and-easy but largely unregulated clinical castrations, penectomies, and similar procedures for at least a couple of decades now.) ... the greater availability of open and official care—far more than horror stories and crackdowns—has led to a drastic decline in demand for cutters, which means there are now fewer of them practicing than there were five or ten years ago.
